Hello,
Take 2 of soft-affinity for Credit2. Not much changed actually:
- what was patch 1, it went in, so the series is shorter; :-)
- in patch 5 ("xen: credit2: optimize runq_candidate() a little bit"), I
changed things according to George's advice;
- patch 2 ("xen: credit2: soft-affinity awareness in gat_fallback_cpu()"),
is the one that changed most. In that case as well, I've accordingly to
what we decided during review.
In fact, all the patches have the tags they need to go in already, *except*
patch 2.
v1 was here:
https://lists.xen.org/archives/html/xen-devel/2017-06/msg01795.html
A git branch is here:
git://xenbits.xen.org/people/dariof/xen.git rel/sched/credit2-soft-aff-v2
